Reference
Endpoint:
boiling point
Type of information:
experimental study
Adequacy of study:
key study
Study period:
17.8.2015
Reliability:
1 (reliable without restriction)
Rationale for reliability incl. deficiencies:
guideline study
Qualifier:
according to guideline
Guideline:
EU Method A.2 (Boiling Temperature)
Deviations:
no
GLP compliance:
yes (incl. QA statement)
Type of method:
differential scanning calorimetry
Key result
Decomposition:
yes
Decomp. temp.:
> 175 °C
Conclusions:
The water evaporation was observed between start temperature and 175°C. The decomposition of the test substance started at the temperature 175°C. Any peaks correspond to the boiling of the test substance were not observed to the temperature at which the thermal decomposition started.Boiling temperature of the test substance, Reactive Blue 234, could not be determined because of thermal degradation of the test substance.
Executive summary:

The boiling temperature of the test substance, Reactive Blue 234 was investigated. The Differential Scanning Calorimetry method was used.

Decomposition of the test substance was observed above 175°C, i.e. 448K. Boiling of the test substance was not observed below the temperature at which decomposition started.

Boiling temperature of the test substance, Reactive Blue 234, could not be determined because of thermal degradation of the test substance.

Description of key information
